Exp 8

Buckling of Columns ME 272 Experiment #8 Objective: The objective of this experiment is to develop an data-based method utilizing the buckling of towers apparatus that will determine the load-deflection function and deprecative loads of a sample column. The developed method is thusly used to determine the load-deflection function and critical loads for a column with various end conditions (pinned-pinned, clamped-pinned, and clamped-clamped). Reference: Sections 10.2 to 10.5 in mechanism of Materials; Beer, Johnston, and DeWolf Apparatus: You will be using the strut utensil for this experiment. Once the test sample is installed into the machine, an axial load is therefore utilise to the column through the hydraulic cylinder. This load is applied by turning the hand crank clockwise. Although the load is cosmos applied axially, the dial indicator produces a slight perspective lode that causes deflection to occur almost immediately. As the column is loaded, the dial indicator will measure the deflection in the beam. The cross member that houses the indicator can be go laterally to place the indicator at the location on the column with maximum deflection. This machine can simulate some(prenominal) pinned and clamped end conditions.

For a clamped end condition, the end of the column is evidently clamped into the fixture. For the pinned end condition, the clamp is tightened without the column in it. The column is thusly slid into the V-shaped groove. Although there will be some side loading from the V-shaped groove, it is negligible, allowing the assumption of a pinned end. Deliverables: 1. Document this experiment with a prescribed lab report following the report guidelines set forth in the ME 272 lab manual. 2. For theory section, present and discuss the equations and the pedigree of the equations that were used to determine the calculated value of Pcr and the experimentally obtained value. 3. For severally end condition, create plots showing the... If you want to get a full essay, order it on our website: Orderessay
